Jismis007,
Welcome to the forum! Many people here believe that hanging and stretching are probably the most effective ways of gaining length. Jelqing has also been effective for many—especially when it is done with a weak erection.
As a newbie, however, you must walk before you can run. I suggest doing the newbie routine for a couple of months before trying anything more ellaborate. This will help to condition your penis and prepare it for more strenuous work later.
Many people get excellent gains from the newbie routine. Don’t rush your progress. I suggest you keep with the newbie routine as long as you are gaining.
